MARKING-MACHINE.

Specification of Letters Patent. Patented NOV. 30, 1920.

Application filed October 12, 1918. Serial No. 257,910.

T 0 all whom it may concern:

Be it known that I, EDWIN W. SMITH, a citizen of the United States,residin at Beverly, in the county of Essex and btate of Massachusetts,have invented certain Improvements in Marking-Machines, of which thefollowing description, in connection with the accompanying drawings, isa specification, like reference characters on the drawings indicatinglike parts in the several figures.

The present invention relates to machines for marking various objects,as portions of shoe uppers, and has to do more particularly withapparatus in which marking members may be set in various positions toproduce different characters.

In such machines the usual expedient is to employ a single settinginstrumentality which is successively brought into cooperation with allthe marking members which are to be set. This time-consuming process isavoided by my invention, which provides means simultaneously movableinto cooperation with different marking members for the independentsetting thereof. By this arrangement, plural members may besimultaneously brought to the desired position with considerable economyof time. As illustrated, the setting means, while capable of actuationindependently in the setting movement, are movable together in theselection of the marking members. Preferably I arrange membersconstituting the setting means oppositely, there being groups of theseopposite members, appearing as alined concentric sleeves, each sleevehaving a projection arranged to enter recesses in the series of markingdisks to be set. The connection between the opposite setting sleeves,which causes their travel together, is shown as consisting of a rodpassing through them, and also as a rod movable in a support and beingjoined to the sleeves. I prefer to so arrange the setting members thatthey normally operate on themore fre quently set marking members. Thereis illustrated herein a series of marking members having less frequentlyset members interposed between those more frequently set, with these andthe setting means spaced to permit the latter to be in normallyoperative relation to the more frequentlv used marking members. Then,when necessary, by moving the setting members through a space equal tothe width of the interposed markmg members only, the entire settingmeans may be brought.v into cooperation with the less frequently setmembers. To guide the operator in setting the marking'members, I haveshown indicating means for detervmining the position of each of thesetting members.

A single one of the several forms which my invention may assume isillustrated in" the accompanying drawing. Here,

Figure l is a side elevation of a marking machine having my inventionapplied thereto;

Fig. 2 is a partial front elevation looking from the left in Fig. 1,with portions in vertical section;

Fig. 3 is a vertical section on the line 33 of Fig. 2; and

Fig. 4 is a detail in front elevation of the index member for thesetting means.

In a frame 10 is supported for oscillation toward and from awork-support 12, a marking head 14, preferably under the influence ofsuitable mechanism driven by power applied to a pulley 16. At theforward extremity of the head betweenseparated supporting walls 18, 18is mounted a series of marking members 20. These marking members areshown in the form of disks rotatable about a tubular spindle 22 fixed atthe lower portion of the forward end of arranged for stamping parts ofshoe uppers,

we have on the first two disks at the right.

tens and unit size designations, followed by the half-size mark disk,then two disks bearing width symbols, after which are two disks formatch marks, and finally six disks with series of digits for the casenumbers.

At least one tooth on each disk, as indicated at 28 in Fig. 3, isshorter than the associated teeth to permit the disk to be set to makeno impression. Heat may be supplied to the disks by some such device asan electrical unit 30 situated within the spindle 22.

Above the marking disks appear setting disks 32, one for each of thedisks 20, arranged between the walls 18, 18 and having alined centralopenings through which pass the setting means for manipulation by thethe setting means consists of members arranged in opposite groups of twoeach. For these members I prefer to employ tubular shafts or sleeves,there being two concentric sleeves in each group, an inner 34 and anouter 36. The outer sleeves are journaled in the walls 18, and throughthe inner passes a rod or shaft 38 holding the groups together. Aspacing washer 40 surrounds the rod 38 between the ends of the sleeves34, its width being preferably equal to that of two of the settingdisks. At the inner extremity of each of the sleeves 34 is a flange 42which is equal in diameter to the outside of the sleeves 36. Upon thesleeves 36, the flanges 42 and the washer 40, the disks 32 are arrangedto turn. They are normally held in the angular position to which theyare set, by spring fingers 44 fixed upon a bar 46 bridging the spacebetween the walls 18, said fingers having enlarged end portions 48 forentering the spaces between the teeth. Upon the inner end of each sleeve36 and upon each of the flanges 42 is a peripheral projection 50. Theseprojections are movable by the longitudinal travel of the settingsleeves through a series of re cesses 52 connected with the centralopenings of the disks 32, these corresponding in number and position toteeth 54 projecting from the disks 32 similarly to the teeth 24 of thedisks 20 and meshing therewith. The length of the sleeves 34 and 36 issuch as to permit the movement of the projections 50 into any of therecesses 52, and fixed upon their outer ends are hand wheels 56, one foreach sleeve, the diameter of the inner pair of wheels being preferablygreater than the outer pair to permit the operator to manipulateconveniently the separate setting sleeves. The hand wheels are heldagainst shoulders upon the sleeves by screws 58 threaded into the endsof the rod 38 and bearing against the outer pair of wheels. Vhen thesleeves are rotated, the projections 50, by their engagement with therecesses 52 which they occupy, turn the corresponding disks 32, andthrough the intermeshing teeth 24 and 54 set the marking disks 20.

In addition to the rod 38, the opposite groups 0]": setting sleeves areconnected by a rod 60 passing through alined openings in upwardextensions 62 of the marking head. This rod is joined to the sleeves 36by arms 64 surrounding said sleeves and bearing against shoulders uponthem, the opposite or upper ends of the arms being secured to the rod'bynuts 66. Fixed to the rod 60 is av me be 6 having an in a ing point foreach of the sleeve projections 50 and in vertical alinement therewith.The ends of. the teeth 54 preferably bear index characters 72corresponding to the dies upon the teeth 24. The parts are so relatedthat when a character 72 is beneath the corresponding index point 70,the like die upon a tooth 24 will be in marking position.

I prefer to have the setting projections of the sleeves normally withinthe recesses of the disks bearing the unit size designations, thehalf-size symbols, and those for the match marks. These characters inmarking shoe uppers are more or less frequently changed during thestamping of the shoes which are to make up a case. The width number,however, customarily remains the same for the entire case, and the casenumber, of course, does not change until the work for a new case is tobe stamped. With the setting means in this position, the operator can,by manipulating a hand wheel at either side of the head, simultaneouslyturn the corresponding disks, by the engagement of the sleeveprojections with the recesses 52, to bring any desired character thereoninto marking position, and can readily shift the grasp to the other pairof wheels to set the disks which these control. If the tens digit alsois to enter into the size mark, the movement of the setting means as awhole, by sliding the sleeves and connecting members together to theright in the head through the width of a single marking disk, rendersthis possible. hen the case is finished, bodily movement of the settingmeans to the left through the width of two marking disks from the normalposition alines the setting projections with the disks bearing the widthdesignations and the first two disks of case numerals, so that theoperator may adjust the disks for the width of shoes of this case andset its two highest numerals. $uccessive movements to the left permitthe setting of the remaining case numerals, whereupon the setting meansmay be restored to its normal position.

Having thus described my invention. what I claim as new and desire tosecure by Letters Patent of the United States is:
